Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate

Laser &Photonics Reviews, EarlyView.
Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, EarlyView.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

Nano Select, EarlyView.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm

First‐Principles Investigation of Zn Doping Impacts on the Structural, Electronic, Mechanical, Thermodynamic, and Optical Properties of α‐NiS for Photocatalytic Activity

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
This study employs first‐principles density functional theory + U calculations to explore the effects of Zn doping on the structural, electronic, and photocatalytic properties of NiS. The results reveal that Zn incorporation narrows the band gap, enhances visible‐light absorption, and promotes efficient charge separation, highlighting Zn–NiS as a ...

Room Temperature Evidence of PtTe2 Topological Semimetal Character

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
We report on a melt growth process for the synthesis of high‐quality PtTe2 crystals, as assessed by X‐ray diffraction and X‐ray photoemission spectroscopy characterization. By angle‐resolved photoemission spectroscopy investigation, we observe the expected topological features at cryogenic temperature and we demonstrate their stability even at room ...
